00:18:410 (3,4,5) - Aside from the unequal distance snap (which i commented about in the general tab), you should refrain from using very sharp flow like this which obstructs a previous object and is still very visible in gameplay.
A suggestion would be to base your flow with wide angles, like http://puu.sh/B6lvc/af601a9b34.png . Of course this isn't the only time this happens, check your map for other instances. Using a simple movement like this is ideal for low difficulties since it won't be too harsh on the player to read and aim.
Some other occurences:
00:22:386 (4,5,6) -
00:26:001 (2,3,4) -
00:28:169 (1) -
00:10:820 (1,2,3) -
00:57:627 (2,3,4,5,6,7) - Sometimes you have groups of circles like this with no rhythm variety. Even if this is a low difficulty, you can still be creative and add some variety such as sliders. This would also benefit gameplay because this can be seen as straining due to the amount of continuous circles in a syncopated rhythm.
